What effect does an unconditional branch have on branch prediction/pipelining? http://www.wrenvironmental.com/commercial/services/pipelining/ Is LOCTR a help? I can imagine the frustration of a programmer trying to correlate a dump with a listing where the author has used LOCTR heavily and wishing that HLASM had an option to generate SYSPRINT in address order rather than in source order. Does HLASM have an instruction to cause cache line alignment? Such an instruction would need to be model-sensitive, perhaps governed by OPTABLE. -- gil
